OIL-BURNER.

Specification of Letters Patent.

Application filed February 28, 1920. Serial No. 362,148.

T 0 a'ZZ fw ,710m it may concern:

Be it known that 1, VAUGHN R. CriannoUnNn, a citizen of the United States o America, residing at `Beaumont, in the county orn Jefferson and State ot Texas, have invented new and useful Improvements in Oil-Burners, of which the following is a specilication.

This invention relates to oil burners and has for its object the provision o'r` a novel form oi' oil burner particularly adapted for using very heavy oil and so constructed as to provide a wide fiat tia-me.

An important object is the provision of a burner of this character which includes a tip and having means whereby oil may be conducted to a slot in the tip and whereby steam may be conducted to and discharged through a second slot in the tip separated,

from the first slot and arranged at an angle thereto whereby the steam will be mixed with the oil exteriorly of the tip, the steam breaking up the oil and mixing therewith so as to form a very readily combustible mixture.

Another object is the provision ot a burner of this character in which the tip is adjustable so that the flame may be directed in any direction in one plane even though the head might be fixed in a certain position.

An additional object is the provision of a burner of this character which will be simple and inexpensive in manufacture, highly efiicient in use, durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which- Figure 1 is a side elevation,

Fig. 2 is a longitudinal sectional view,

Fig. 3 is an end elevation, and

Fig. 1 is a longitudinal sectional view at right angles to Fig. 2.

Referring more particularly to the draw ings, the numerals 10 and 11 designate the two sections of the burner. The section 10 constitutes the top when the burner is used for general back shot use under water tube boilers. The section 10 is provided with a longitudinally ext-ending passage 12 which is internally threaded at its outer end for engagement therein of a pipe 13 conducting oil. Adjacent its other end the section 10 is Jformed with a cylindrical recess 14 coinmunicating with the adjacent end ot' the passage 12. Intermediate its ends and upon its underside tl e section 1() is formed with an enlargement 15 which is provided with a threaded hole 16.

The section 11 is provided at one end with a recess 17 opposite to the recess 14 and communicating with this recess 17 is a hole 18 internally threaded for engagement therein oi' a steam conducting pipe 19. Passing through a smooth hole 2O in the central portion of the section 11, is a cap screw 21 which is threaded into the hole 16. Threaded through the other end portion of the section 11 is a set screw 22 which has its end engaging against the under face of the section 10.

Disposed between the sections 10 and 11 is a tip formed as a cylindrical shell 23 having its ends open and seated within the recesses 14 and 17. This shell is provided centrally with a transverse partition 241 and is formed in its periphery at one side of the partition with a slot 25 and at the other side of the partition with a slot 26 which is inclined with respect to the slot 25, the inclination in actual practice being` preferably 80 and 30.

In the operation of the burner it is of course understood that it is supported within any suitable device for. holding it stationary. Oil enters the passage 12 and upper half of the tip 23 through the pipe 13 and passage 12 and passes out through the slot 25. Steam enters the device through the pipe 19 and passes into the lower halt of the tip and out through the inclined slot 26. The steam does not mix with the oil until both are outside of the tip and the blow of the steam into the oil at an angle thoroughly breaks up the oil and mixes with it so as to produce a highly combustible mixture.

The provision of the cap screw 21 and set screw 22 is to permit adjustment of the tip. When these screws are loosened it will be observed that the tip 23 may be rotated with the recesses 14C and 17 so that the slots 25 and 26 may be arranged to discharge in any direction in one plane. When the slots are at the proper position, tightening of the screws 21 and 22 will cause the sections 10 and 11 to grip the tip firmly and hold it in the proper adjusted position.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a very simply constructed and yet highly efficient burner by means of which very heavy oil may be satisfactorily used as a fuel.

While I have shown and described the preferred embodiment of my invention it is of course to be understood that I reserve the right to make such changes in the forni, construction, and arrangement of parts as will not depart from the Vspirit of the invention or the scope of the subjoined claim` Having thus described my invention, I claim:

An oil burner comprising a section provided at one end With a recess and provided with an oil conducting passage leading into said recess, a second` section disposed in spaced relation to Said first named section and provided with a recess opposite said first named rece and further provided with a steam conducting hole leading into its recess, a tip formed as a shell having its ends disposed Within said recesses and proi vided intermediate its ends with a partition, the shell having its periphery provided with a circumferential slot at one side of the partition and provided at the other side of' the partition with a second circumferential slot disposed at au angle Withrespect to the rst named slot, and means for clamping said tip between said sections, said means com prising a cap screw passing through a hole in the second named section and threaded into the first named section, and a set screw threaded through the second namedsection and engaging the rst named section.

In testimony Whereoi'I aiX my signature.
